This study was conducted to examine the effect of mefenamic acid for treatment of PDA in premature newborns. Ductus arteriosus is reopened by locally produced prostaglandin E2 in a premature newborn during hypoxia. Mefenamic acid is one of non-steroidal antiinflammatory drugs acting by inhibition of cyclo-oxygenase in the prostaglandin synthesis pathway. For three premature newborns with PDA, we administered mefenamic acid and evaluated them with echocardiography to study the effect of mefenmic acid for closure of PDA. In all three babies, ductus arteriosus was closed successfully. We feel that mefenamic acid is safe and effective medication for treatment of PDA in premature newborns, but further-study need to be conducted with larger numbers of cases to confirm this effect.

Relining and rebasing are essential for long-term success and oral health in removable prosthodontics. Major features of failures between metal base and relining resins are adhesive failure due to lack of chemical bonding. The purpose of this study was to find a better metal primer and metal surface treatment method that enhance the bonding strength with relining resin materials. The surfaces of ticonium alloys were treated with 25micrometer sandblasting (Group A), stone wheel (Group B), stone wheel and EZ oxisor (Group C), 75micrometer sandblasting (Group D) and EZ oxisor application after 75micrometer sandblasting (Group E). They were subdivided into no primer application (Group I), MR bond application (Group II) and Metafast bonding liner (Group III). Then specimens were completed though being bonded with relining resins. The specimens were stored in 38degrees C water for 48 hours and tensile strength was measured using the universal testing machine. The results were as follows, 1. Primer application groups showed higher bond strength than no primer application group(p<0.05). 2. In comparison with primer application groups, MR bond group showed higher bond strength than Meta fast bonding liner application group(p<0.05). 3. In comparison with surface treatment methods. Bond strengths of group A and B were significantly different with group C, D, and E, and group C were significantly different with group D, and E in no primer application group(p<0.05). In primer application groups, group A, B, C were significantly different with group D and E(p<0.05). According to results of this study, Metal primer application and metal surface roughening were considered to be advantageous for relining of metal base dentures.

The association of colonic atresia in patients with Down syndrome is a rare anomaly. The incidence of congenital atresia of the gastrointestinal tract has been estimated to be about one in 1500 births. Colonic atresia is rarer still, and is throut to comprise about 5% to 10% of this group. This intestinal atresia occurs in about 30% to 50% of patient with Down syndrome. We experienced a case of Down syndrome associated with colonic atresia in a 1 day old male. His initial chief complaints at the admission were severe abdominal distension and Down appearance. Diagnosis was confirmed by chromosomal study and operative laparotomy with end-to-end ileodescending colostomy. We report the case with brief review of related literatures.

Sjogren-Larsson Syndrome is a rare disorder chracterized by congenital icthyosis, spastic diplegia or tetraplegia and mental retardation. The inheritance is autosomal recessive, due to deficiency of alcohol dehydrogenase activity of fatty acid matabolism. We have experienced a case of Sjogren-Larsson Syndrome in a 16 month-old male children who have dried thick skin, developmental delay, and spastic diplegia. He also has glistening spot on macula area with irregular high voltage slow wave (2-3Hz) on electroencephalography. From Biopsy finding, Lamella ictyosis with acanthosis and hyperkeratosis in epithelium is shown. He was much improved clinically for skin lesion and developmental status with etretinate supplement. We report the case with brief review of related literatures.

The cumulative incidence of breast cancer in Korea is low, being about one-fifth of that in the United States. This low incidence has been mainly explained by environmental factors, and recently, however, racial variations in the disease-causing genes should also be considered. The BRCA1 is one of the common genes involved in early-onset breast cancer and/or ovarian cancer in the United States and Northern Europe. However, the involvement of BRCA1 in Korean'breast cancer patients are still unclear. We performed germline mutation screening of the BRCA1 gene by DNA single strand conformation polymorphism (SSCP) analysis. We examined 27 breast cancer patients who were diagnosed less than 35 years by age including two cases with family history of breast cancer. Our study showed no germline mutation at the exons 2, 11 and 20, which were known as the supreme susceptible regions of BRCA1 mutations. Even though our cases did not fulfilled the criteria of familial breast/ovarian cancer, the proprotion of families who inherit the mutated BRCA1 allele seems to be very small and might be negligible among Korean population. Therefore, it is considered that the BRCA1 itself cannot be a major susceptibility gene and the contributions of other genes might be important for the breast cancer.

PURPOSE: To evaluate CT findings of normal anatomic alteration after neck dissection. MATERIALS AND METHODS: The postoperative CT findings were retrospectively reviewed in 40 patients with neck dissection, comparing to preoperative CT. There were 28 patients with radical neck dissection and 12 patients with modified radical neck dissection or selective neck dissection. In addition to the neck dissection, 10 patients had undergone pectoralis major myocutaneous flap reconstruction, 20 patients taken laryngectomy, and 25 patients treated with radiotherapy. RESULTS: The typical CT findings of radical neck dissection were non-visualization of internal jugular vein and sternocleidomastoid muscle(28/28), ipsilateral neck flattening(26/28), and trapezius muscular atrophy(12/28). The other non-specific findings were tissue plane eftacement, subcutaneous reticular pattern, platysma muscle thickening, and adjacent soft tissue contrast enhancement which was the only evidence of previous operation in the cases of modified radical neck dissection or selective neck dissection. Reconstruction with myocutaneous flap was shown as ipsilateral bulk of fat and muscle(10/10). In cases with radiation therapy there was much increased density of submandibular gland(12/25). 15 patients showed recurrence on follow up CT scan, including regional metastasis in 10, stomal recurrence in two, and residual mass at primary site in three patients. CONCLUSION: CT is useful in evaluation of patients with neck dissection and in whom postoperative change impese diagnostic problem.

Purpose:
This study evaluated the clinical and radiological outcomes of TFNA (Trochanteric Fixation NailAdvanced; Depuy Synthes) for the treatment of proximal femur fractures.
Materials and Methods:
This was a retrospective study of 64 patients diagnosed with a proximal femur fracture from January 2019 to November 2019. The patient’s demographic data, preoperatively and postoperatively Koval grade, modified Harris hip score, EQ-5D (Euro-Qol-5 Dimension), sliding and advancement of the blade, radiologic outcome, and complications were investigated.
Results:
Fifty patients were available for evaluation at one year postoperatively. The patients reported the following: the Koval grade decreased after surgery; the modified Harris hip score decreased from 78.56±8.88 to 72.74±6.59 (p=0.149); the mean EQ-5D decreased from 0.75±0.09 to 0.72±0.06 (p=0.000). Satisfactory reduction was achieved on a postoperative radiographic examination in 47 patients in six months. Complications occurred in seven cases.
Conclusion
TFNA is considered an appropriate implant for treating intertrochanteric fractures of the femur with a minimum follow-up of one year.
